Serbia sees wider coverage as Yettel activates 5G

Yettel has launched its 5G network in Serbia, offering higher speeds, lower latency, and support for large numbers of connected devices. Customers need a 5G-ready handset and coverage access, which currently spans major cities and tourist areas. The operator plans wider expansion as deployment progresses.

The service uses recently acquired spectrum, with 5G delivered across the 700 MHz low band and the 3.5 GHz mid band. The frequencies support stronger indoor reach and higher-capacity performance. Yettel says the combination will improve everyday mobile connectivity and enable new digital services.

Use cases include faster downloads, smoother streaming, and more responsive cloud-based gaming. Lower latency will also support remote work and IoT applications. The company expects the network to underpin emerging services that rely on real-time communication and consistent mobile performance.

Yettel forms part of the e& PPF Telecom Group and operates more than 130 retail locations alongside its digital channels. The company says the 5G rollout complements ongoing efforts to modernise national infrastructure. It also aims to maintain strong service quality across urban and regional areas.

The network received the umlaut ‘Best in Test’ award in 2025, marking a ninth consecutive national win. Yettel frames 5G as the next stage of its technological development. The operator expects the upgrade to strengthen the broader digital ecosystem of Serbia and improve long-term connectivity options.

Meta expands global push against online scam networks

The US tech giant, Meta, outlined an expanded strategy to limit online fraud by combining technical defences with stronger collaboration across industry and law enforcement.

The company described scams as a threat to user safety and as a direct risk to the credibility of its advertising ecosystem, which remains central to its business model.

Executives emphasised that large criminal networks continue to evolve and that a faster, coordinated response is essential instead of fragmented efforts.

Meta presented recent progress, noting that more than 134 million scam advertisements were removed in 2025 and that reports about misleading advertising fell significantly in the last fifteen months.

It also provided details about disrupted criminal networks that operated across Facebook, Instagram and WhatsApp.

Facial recognition tools played a crucial role in detecting scam content that utilised images of public figures, resulting in an increased volume of removals during testing, rather than allowing wider circulation.

Cooperation with law enforcement remains central to Meta’s approach. The company supported investigations that targeted criminal centres in Myanmar and illegal online gambling operations connected to transfers through anonymous accounts.

Information shared with financial institutions and partners in the Global Signal Exchange contributed to the removal of thousands of accounts. At the same time, legal action continued against those who used impersonation or bulk messaging to deceive users.

Meta stated that it backs bipartisan legislation designed to support a national response to online fraud. The company argued that new laws are necessary to weaken transnational groups behind large-scale scam operations and to protect users more effectively.

A broader aim is to strengthen trust across Meta’s services, rather than allowing criminal activity to undermine user confidence and advertiser investment.

Mistral AI unveils new open models with broader capabilities

Yesterday, Mistral AI introduced Mistral 3 as a new generation of open multimodal and multilingual models that aim to support developers and enterprises through broader access and improved efficiency.

The company presented both small dense models and a new mixture-of-experts system called Mistral Large 3, offering open-weight releases to encourage wider adoption across different sectors.

Developers are encouraged to build on models in compressed formats that reduce deployment costs, rather than relying on heavier, closed solutions.

The organisation highlighted that Large 3 was trained with extensive resources on NVIDIA hardware to improve performance in multilingual communication, image understanding and general instruction tasks.

Mistral AI underlined its cooperation with NVIDIA, Red Hat and vLLM to deliver faster inference and easier deployment, providing optimised support for data centres along with options suited for edge computing.

A partnership that introduced lower-precision execution and improved kernels to increase throughput for frontier-scale workloads.

Attention was also given to the Ministral 3 series, which includes models designed for local or edge settings in three sizes. Each version supports image understanding and multilingual tasks, with instruction and reasoning variants that aim to strike a balance between accuracy and cost efficiency.

Moreover, the company stated that these models produce fewer tokens in real-world use cases, rather than generating unnecessarily long outputs, a choice that aims to reduce operational burdens for enterprises.

Mistral AI continued by noting that all releases will be available through major platforms and cloud partners, offering both standard and custom training services. Organisations that require specialised performance are invited to adapt the models to domain-specific needs under the Apache 2.0 licence.

The company emphasised a long-term commitment to open development and encouraged developers to explore and customise the models to support new applications across different industries.

Public backlash grows as Coupang faces scrutiny over massive data leak

South Korea is facing broader concerns about data governance following Coupang’s confirmation of a breach affecting 33.7 million accounts. Investigators say the leak began months before it was detected, highlighting weak access controls and delayed monitoring across major firms.

Authorities believe a former employee exploited long-valid server tokens and unrevoked permissions to extract customer records. Officials say the scale of the incident underscores persistent gaps in offboarding processes and basic internal safeguards.

Regulators have launched parallel inquiries to assess compliance violations and examine whether structural weaknesses extend beyond a single company. Recent leaks at telecom and financial institutions have raised similar questions about systemic risk.

Public reaction has been intense, with online groups coordinating class-action filings and documenting spikes in spam after the exposure. Many argue that repeated incidents show a more profound corporate reluctance to invest meaningfully in security.

Lawmakers are now signalling plans for more substantial penalties and tighter oversight. Analysts warn that unless companies elevate data protection standards, South Korea will continue to face cascading breaches that damage public trust.

Amazon rolls out Trainium3 AI chip to challenge Nvidia’s dominance

AWS has launched its in-house AI processor, Trainium3, marking a fresh push to compete with established players in the AI-hardware market. The chip and its associated UltraServer platform were unveiled at the launch event in Las Vegas.

According to Amazon, servers powered by Trainium3 deliver more than four times the performance of the previous generation while using around 40% less energy. Several AI firms, including startups working on large language models, are already utilising the new hardware to reduce their inference or training costs.

Looking ahead, AWS has signalled plans for a follow-up chip, Trainium4, which is expected to integrate with Nvidia’s NVLink Fusion interconnect technology. That would permit hybrid deployments combining Amazon’s ASICs with traditional GPUs, potentially appealing to AI workloads already built around Nvidia’s ecosystem.

The move highlights a broader trend: major tech firms are increasingly investing in their own AI infrastructure, aiming to reduce dependence on dominant vendors and lower costs. As AWS scales out its custom chips, the AI infrastructure market is poised to become more diverse with price-performance and energy efficiency as key differentiators, rather than raw hardware dominance alone.

OpenAI faced questions after ChatGPT surfaced app prompts for paid users

ChatGPT users complained after the system surfaced an unexpected Peloton suggestion during an unrelated conversation. The prompt appeared for a Pro Plan subscriber and triggered questions about ad-like behaviour. Many asked why paid chats were showing promotional-style links.

OpenAI said the prompt was part of early app-discovery tests, not advertising. Staff acknowledged that the suggestion was irrelevant to the query. They said the system is still being adjusted to avoid confusing or misplaced prompts.

Users reported other recommendations, including music apps that contradicted their stated preferences. The lack of an option to turn off these suggestions fuelled irritation. Paid subscribers warned that such prompts undermine the service’s reliability.

OpenAI described the feature as a step toward integrating apps directly into conversations. The aim is to surface tools when genuinely helpful. Early trials, however, have demonstrated gaps between intended relevance and actual outcomes.

The tests remain limited to selected regions and are not active in parts of Europe. Critics argue intrusive prompts risk pushing users to competitors. OpenAI said refinements will continue to ensure suggestions feel helpful, not promotional.

Regulators question transparency after Mixpanel data leak

Mixpanel is facing criticism after disclosing a security incident with minimal detail, providing only a brief note before the US Thanksgiving weekend. Analysts say the timing and lack of clarity set a poor example for transparency in breach reporting.

OpenAI later confirmed its own exposure, stating that analytics data linked to developer activity had been obtained from Mixpanel’s systems. It stressed that ChatGPT users were not affected and that it had halted its use of the service following the incident.

OpenAI said the stolen information included names, email addresses, coarse location data and browser details, raising concerns about phishing risks. It noted that no advertising identifiers were involved, limiting broader cross-platform tracking.

Security experts say the breach highlights long-standing concerns about analytics companies that collect detailed behavioural and device data across thousands of apps. Mixpanel’s session-replay tools can be sensitive, as they can inadvertently capture private information.

Regulators argue the case shows why analytics providers have become prime targets for attackers. They say that more transparent disclosure from Mixpanel is needed to assess the scale of exposure and the potential impact on companies and end-users.

Irish regulator probes an investigation into TikTok and LinkedIn

Regulators in Ireland have opened investigations into TikTok and LinkedIn under the EU Digital Services Act.

Coimisiún na Meán’s Investigations Team believes there may be shortcomings in how both platforms handle reports of suspected illegal material. Concerns emerged during an exhaustive review of Article 16 compliance that began last year and focused on the availability of reporting tools.

The review highlighted the potential for interface designs that could confuse users, particularly when choosing between reporting illegal content and content that merely violates platform rules.

An investigation that will examine whether reporting tools are easy to access, user-friendly and capable of supporting anonymous reporting of suspected child sexual abuse material, as required under Article 16(2)(c).

It will also assess whether platform design may discourage users from reporting material as illegal under Article 25.

Coimisiún na Meán stated that several other providers made changes to their reporting systems following regulatory engagement. Those changes are being reviewed for effectiveness.

The regulator emphasised that platforms must avoid practices that could mislead users and must provide reliable reporting mechanisms instead of diverting people toward less protective options.

These investigations will proceed under the Broadcasting Act of Ireland. If either platform is found to be in breach of the DSA, the regulator can impose administrative penalties that may reach six percent of global turnover.

Coimisiún na Meán noted that cooperation remains essential and that further action may be necessary if additional concerns about DSA compliance arise.

OpenAI expands investment in mental health safety research

Yesterday, OpenAI launched a new grant programme to support external research on the connection between AI and mental health.

An initiative that aims to expand independent inquiry into how people express distress, how AI interprets complex emotional signals and how different cultures shape the language used to discuss sensitive experiences.

OpenAI also hopes that broader participation will strengthen collective understanding, rather than keeping progress confined to internal studies.

The programme encourages interdisciplinary work that brings together technical specialists, mental health professionals and people with lived experience. OpenAI is seeking proposals that can offer clear outputs, such as datasets, evaluation methods, or practical insights, that improve safety and guidance.

Researchers may focus on patterns of distress in specific communities, the influence of slang and vernacular, or the challenges that appear when mental health symptoms manifest in ways that current systems fail to recognise.

The grants also aim to expand knowledge of how providers use AI within care settings, including where tools are practical, where limitations appear and where risks emerge for users.

Additional areas of interest include how young people respond to different tones or styles, how grief is expressed in language and how visual cues linked to body image concerns can be interpreted responsibly.

OpenAI emphasises that better evaluation frameworks, ethical datasets and annotated examples can support safer development across the field.

Applications are open until 19 December, with decisions expected by mid-January. The programme forms part of OpenAI’s broader effort to invest in well-being and safety research, offering financial support to independent teams working across diverse cultural and linguistic contexts.

The company argues that expanding evidence and perspectives will contribute to a more secure and supportive environment for future AI systems.
